Abstract
Description
La présente invention concerne un procédé d'incorporation dans des pellets de principes actifs. Elle concerne plus particulièrement l'incorporation dans des pellets de principes actifs protégés vis à vis des enzymes de la panse des ruminants. Elle concerne encore plus particulièrement la préparation de pellets destinés à être incorporés à l'alimentation des ruminants.The present invention relates to a process for incorporating active ingredient pellets into pellets. It relates more particularly to the incorporation into pellets of active principles protected with respect to the enzymes of the rumen of the rumen. It also relates more particularly to the preparation of pellets intended to be incorporated into the feed of ruminants.
On entend par "pellet" un granulé nutritif pour les animaux obtenu soit par extrusion à travers une filière d'un mélange d'aliments soit par une autre technique. Ils se présentent sous forme de bâtonnets de préférence cylindrique présentant notamment des dimensions moyennes de 4 à 20 mm de long et de 4 à 10 mm de diamètre. Ils sont largement utilisés, car ils sont faciles à manipuler, à administrer et non poussiérants.The term “pellet” is understood to mean a nutritious granule for animals obtained either by extrusion through a die of a mixture of foodstuffs or by another technique. They are in the form of rods, preferably cylindrical, having in particular average dimensions from 4 to 20 mm in length and from 4 to 10 mm in diameter. They are widely used because they are easy to handle, administer and non-dusty.
Le problème que cherche à résoudre la présente invention consiste à incorporer dans des "pellets" destinés à l'alimentation animale des granulés contenant des composés utiles à leur alimentation et/ou à la thérapeutique de ces animaux, mais qui ne peuvent subir la pelletisation du fait de leur sensibilité à la température, à la pression et au cisaillement. En effet, les appareils de pelletisation sont des appareils qui permettent la mise en forme par forçage d'un mélange alimentaire à travers une filière en présence de vapeur d'eau.The problem which the present invention seeks to solve consists in incorporating into "pellets" intended for animal feed granules containing compounds useful for their feeding and / or for the therapy of these animals, but which cannot undergo pelletization of the made of their sensitivity to temperature, pressure and shear. Indeed, pelletizing devices are devices which allow the shaping by forcing of a food mixture through a die in the presence of water vapor.
Ce mélange est passé à travers une plaque perforée (la filière) par le moyen d'une presse qui force la masse à extruder à travers les orifices de la plaque. A la sortie de la filière, les cylindres obtenus sont coupés par un moyen mécanique ou spontanément. Lors du passage forcé à travers la filière, les produits à faible résistance thermique ou mécanique subissent une dégradation due à la fois à la pression exercée et à la chaleur provoquée à la fois par le frottement et par l'addition de vapeur favorable à la cohésion des divers ingrédients farineux des aliments de base.This mixture is passed through a perforated plate (the die) by means of a press which forces the mass to extrude through the orifices of the plate. At the outlet of the die, the cylinders obtained are cut by mechanical means or spontaneously. During the forced passage through the die, products with low thermal or mechanical resistance undergo degradation due to both the pressure exerted and the heat caused both by friction and by the addition of steam favorable to cohesion various floury ingredients in basic foods.
Ce problème a déjà été évoqué dans diverses antériorités. On peut citer parmi ces antériorités la demande de brevet européen publiée sous la numéro EP 231 817 qui décrit un procédé de préparation "d'aliments agglomérés" à base de vitamines ou de composés indispensables à la santé humaine ou animale. Dans l'art antérieur, il était connu que lorsque ces composés subissent une élévation de température lors du passage dans des appareils de pelletisation, ils sont détruits au moins partiellement. En effet, les composés à faible résistance thermique ou mécanique sont souvent mélangés pour leur mise en forme à de la mélasse et subissent l'action de la vapeur afin d'assurer leur cohésion. L'action simultanée de la vapeur et de la pression les détruit. La demande de brevet EP 231 817 a permis de résoudre le problème de fabrication de ces "aliments agglomérés" par pulvérisation sur un noyau de base d'une solution ou d'une suspension de la vitamine ou des vitamines ou du médicament et éventuellement d'un corps gras. Ce procédé ne permet qu'un enrobage du corps de base par la vitamine avec ou sans corps gras. Ledit procédé est facile à mettre en oeuvre à partir de produits pulvérulents ou liquides tels que les vitamines ou les médicaments. Ces produits sont ainsi faciles à mettre en oeuvre sous forme de solution ou d'une suspension. Il n'en est pas de même lorsque l'on forme des "granulés nutritifs agglomérés" dans lesquels la matière sensible à la chaleur et/ou à la compression se présente elle-même sous forme de granulés de diamètre moyen d'environ 0,3 à 5 mm ce qui est le cas dans la présente invention.This problem has already been mentioned in various prior art. Among these prior art, mention may be made of the European patent application published under the number EP 231 817 which describes a process for the preparation of "agglomerated foods" based on vitamins or compounds essential for human or animal health. In the prior art, it was known that when these compounds undergo a rise in temperature when passing through pelletizing devices, they are destroyed at least partially. Indeed, the compounds with low thermal or mechanical resistance are often mixed for their shaping with molasses and undergo the action of steam in order to ensure their cohesion. The simultaneous action of steam and pressure destroys them. Patent application EP 231 817 has made it possible to solve the problem of manufacturing these "agglomerated foods" by spraying onto a basic core of a solution or a suspension of the vitamin or vitamins or of the drug and possibly of a fatty substance. This process allows only a coating of the basic body with the vitamin with or without fatty substance. Said method is easy to carry out using pulverulent or liquid products such as vitamins or medicines. These products are thus easy to use in the form of a solution or a suspension. It is not the same when forming "agglomerated nutritive granules" in which the material sensitive to heat and / or to compression is itself in the form of granules with an average diameter of about 0, 3 to 5 mm which is the case in the present invention.
Il est également décrit dans le brevet français publié sous le numéro FR 2 338 653 un procédé de préparation de produits alimentaires sur lesquels sont pulvérisés une suspension d'enzyme de préférence de protéases dans une matière grasse liquide ou fondue. Ce procédé apporte le même enseignement que la demande européenne préalablement évoquée et ne permet d'obtenir que des "pellets" sur lesquels la substance thermosensible est déposée en périphérie par un phénomène de pulvérisation.There is also described in the French patent published under the number FR 2 338 653 a process for the preparation of food products onto which an enzyme suspension preferably of proteases is sprayed in a liquid or molten fat. This process provides the same teaching as the European application previously mentioned and allows only "pellets" to be obtained on which the heat-sensitive substance is deposited on the periphery by a spraying phenomenon.
Il est connu selon le brevet EP-A-100 974 de préparer des pellets de granulés stables à la chaleur et à la vapeur d'eau contenant un complexe de zinc et d'amino acide stable dans le rumen. La stabilité au rumen et à la chaleur est apportée par la modification de la structure chimique de l'amino acide.It is known according to patent EP-A-100 974 to prepare pellets of granules stable to heat and water vapor containing a complex of zinc and amino acid stable in the rumen. Rumen and heat stability is provided by the modification of the chemical structure of the amino acid.
Il est encore connu selon le brevet US 4 066 754 de préparer des bolus contenant des granulés d'un principe actif et d'un matériau dense protégé par un enrobage de zéine, de la zéine pulvérulante et un agent lubrifiant. Ces granulés ne contiennent pas de matière fusible et la protection n'est pas détruite par la compression.It is also known from US Pat. No. 4,066,754 to prepare boluses containing granules of an active principle and of a dense material protected by a coating of zein, pulverulent zein and a lubricating agent. These granules do not contain fusible material and the protection is not destroyed by compression.
Il est enfin connu selon le brevet US 3 413 118 de préparer des granulés d'urée ou de sels d'ammonium libérables dans le rumen qui sont enrobés d'une émulsion et de luzerne et peuvent être pelletisés. Ces granulés ne répondent pas aux objectifs de la présente invention car ils ne sont pas rumen-résistant.Finally, it is known according to US Pat. No. 3,413,118 to prepare granules of urea or ammonium salts releasable in the rumen which are coated with an emulsion and with alfalfa and can be pelletized. These granules do not meet the objectives of the present invention because they are not rumen-resistant.
Le problème qu'a cherché à résoudre la présente invention est la mise sous forme de "pellets", directement assimilables par les animaux, d'additifs destructibles au niveau de la panse des ruminants tels que les aminoacides, les vitamines ainsi que d'autres additifs nutritionnels ou médicamenteux.The problem that the present invention has sought to solve is the form of "pellets", directly assimilable by animals, of destructible additives in the rumen of ruminants such as amino acids, vitamins and others nutritional or medicinal additives.
Il est connu par exemple, que certains aminoacides sont essentiels dans l'alimentation des ruminants car ils sont limitants dans l'apport nutritionnel journalier. Il en est ainsi notamment de la méthionine et de la lysine. Ces substances, lorsqu'elles sont administrées aux ruminants par voie orale sont détruites dans la panse par l'action des enzymes digestives et des microorganismes présents dans cet organe. Il a été découvert que pour que ces composés soient utilisables et bénéfiques pour l'animal, il fallait les protéger par une substance leur permettant de traverser le rumen sans dommage mais délitable au niveau ou après la caillette de façon à libérer la substance active dans l'intestin et permettre ainsi son passage dans l'organisme.It is known, for example, that certain amino acids are essential in the diet of ruminants because they are limiting in the daily nutritional intake. This is particularly the case for methionine and lysine. These substances, when administered to ruminants by the oral route, are destroyed in the rumen by the action of digestive enzymes and microorganisms present in this organ. It was discovered that for these compounds to be usable and beneficial for the animal, it was necessary to protect them by a substance allowing them to cross the rumen without damage but disintegrable at the level or after the abomasum so as to release the active substance in the intestine and thus allow its passage through the body.
Généralement, les compositions d'enrobage connues sont constituées de l'association d'une substance sensible aux variations du PH, choisie en particulier parmi des copolymères basiques synthétiques, avec des substances hydrophobes qui peuvent être choisies, par exemple, parmi les acides gras ou leurs dérivés et les polymères hydrophobes. De telles compositions sont décrites, par exemple, dans les brevets français FR 78 23966 (2 401 620), FR 78 23968 (2 401 621) ou FR 81 18954 (2 514 261).Generally, the known coating compositions consist of the association of a substance sensitive to variations in pH, chosen in particular from synthetic basic copolymers, with hydrophobic substances which can be chosen, for example, from fatty acids or their derivatives and hydrophobic polymers. Such compositions are described, for example, in French patents FR 78 23966 (2 401 620), FR 78 23968 (2 401 621) or FR 81 18954 (2 514 261).
Parmi les principaux groupes d'agents d'enrobage, on peut citer à titre d'exemples les copolymères de la vinyl pyridine et du styrène avec une substance hydrophobe de préférence l'acide stéarique et/ou un polymère non hydrosoluble, par exemple l'éthylcellulose.Among the main groups of coating agents, examples which may be mentioned are the copolymers of vinyl pyridine and styrene with a hydrophobic substance, preferably stearic acid and / or a non-water-soluble polymer, for example ethylcellulose.
On peut aussi citer le groupe d'agents d'enrobage à digestion enzymatique, tels que le chitosan et/ou la zéïne, associé à une substance hydrophobe de préférence l'acide stéarique et éventuellement à un polymère non hydrosoluble de préférence l'éthylcellulose.Mention may also be made of the group of coating agents with enzymatic digestion, such as chitosan and / or zein, associated with a hydrophobic substance preferably stearic acid and optionally with a non-water-soluble polymer preferably ethylcellulose.
Les granulés de principes actifs protégés obtenus se présentent sous forme de particules plus ou moins sphériques ayant un diamètre moyen compris entre 0,3 et 5 mm, de préférence d'environ 2 mm.The granules of protected active ingredients obtained are in the form of more or less spherical particles having an average diameter of between 0.3 and 5 mm, preferably around 2 mm.
Il est inenvisageable de pouvoir pulvériser des granulés de cette dimension sur des "pellets" de matière nutritive. Ces granulés ne peuvent pas non plus être introduits dans des appareils de pelletisation car l'enrobant subit des aggressions telles que l'abrasion, le cisaillement, l'élévation de température, l'adjonction de vapeur d'eau et la pression qui entraînent une dégradation au moins partielle de l'enrobant et donc une non-stabilité des principes actifs dans le rumen lors de l'ingestion par l'animal.It is unthinkable to be able to spray granules of this size on "pellets" of nutritive material. These granules can also not be introduced into pelletizing devices because the coating undergoes aggressions such as abrasion, shearing, temperature rise, the addition of steam and pressure which cause a at least partial degradation of the coating agent and therefore non-stability of the active ingredients in the rumen during ingestion by the animal.
Il semblait donc impossible de faire ingérer aux ruminants lesdits principes actifs protégés autrement qu'en les dispersant dans l'aliment ce qui pose des problèmes d'homogénéité, de concentration et de distribution.It therefore seemed impossible to make the ruminants ingest said protected active ingredients other than by dispersing them in the feed, which poses problems of homogeneity, concentration and distribution.
La présente invention a permis d'atteindre cet objectif.

Les pellets spéciaux selon l'invention présentent au moins trois caractéristiques qui les rendent utiles pour l'alimentation des ruminants:
- 1/ Ils sont miscibles en toutes proportions avec les aliments granulés généralement distribués à l'animal en supplémentation de la ration fourragère de base. C'est à dire qu'ils peuvent supporter sans démélange les différentes étapes de manutention auxquelles sont soumis les aliments granulés, et s'intègrent dans la chaine de distribution de l'aliment.
- 2/ La perte de protection des principes actifs protégés y est limitée lors de la mise en forme.
- 3/ Les "pellets spéciaux selon l'invention" ainsi réalisés se délitent rapidement dans le rumen, et évitent une perte de protection des principes actifs inclus, par mastication lors de la rumination. Les principes actifs protégés peuvent alors continuer librement le transit.
- 1 / They are miscible in all proportions with the granulated feeds generally distributed to animals in addition to the basic feed ration. That is to say that they can withstand the various handling steps to which the granulated food is subjected without mixing, and are integrated into the food distribution chain.
- 2 / The loss of protection of the protected active ingredients is limited there during the shaping.
- 3 / The “special pellets according to the invention” thus produced disintegrate quickly in the rumen, and avoid a loss of protection of the active ingredients included, by chewing during rumination. Protected active ingredients can then freely continue transit.
L'aptitude à la miscibilité avec les aliments granulés traditionnels dépend essentiellement de la forme et de la densité des produits réalisés et ne présente pas de difficulté pour l'homme de l'art.The ability to miscibility with traditional granulated foods depends essentially on the shape and density of the products produced and does not present any difficulty for those skilled in the art.

Le taux de libération représente la proportion centésimale de principes actifs libérés au cours du test. La taille de la prise d'essai est fonction de la nature du principe actif et de sa teneur. Pour les acides aminés cités en exemples, le test est réalisé sur environ 6 g d'équivalent.The level of protection which characterizes the protected principles is equal to 100 minus the rate of release observed in vitro by measuring the release of the active principles, after 24 h in 1000 ml of pH 6 buffer, with stirring 300 rpm, at 40 ° C. The release rate represents the percentage percentage of active ingredients released during the test. The size of the test portion depends on the nature of the active ingredient and its content. For the amino acids cited in examples, the test is carried out on approximately 6 g of equivalent.
Le taux de protection doit naturellement être le plus élevé possible.The protection rate must of course be as high as possible.
Le délitement des "pellets spéciaux selon l'invention" dans le rumen qui permet la restitution des principes actifs protégés, est évalué par incubation dans le rumen de bovins fistulés au moyen de sachets en tissu de nylon de vide de maille de 350 microns. Le temps de délitement doit être le plus faible possible, et en particulier inférieur à 48 h.The disintegration of the "special pellets according to the invention" in the rumen which allows the return of the protected active ingredients, is evaluated by incubation in the rumen of fistulated bovines by means of sachets of nylon mesh vacuum fabric of 350 microns.
